I'm having the same issue, from since I updated to the last patch... I'm just not able to sign in.... actually it does sign in but it signs off right away... most applications won't work because of this... getting super frustrating Please some help would be appreciated! Thanks

who is your ISP? did you get a new gateway/modem with them in that time it started happening? You should also see what you DNS addresses are for your ISP. I have never heard of openDNS, but when I searched those addresses it came up to them. If you are using a gateway with your provider and you are setting it up to DMZ mode you must make sure that you aren't connecting your wifi devices to the gateway as well. It will try to share 1 IP to them all then just become conflicted and boot you off. Only 1 device should be connected to the gateway then, that should be your router. Login to your router and check to make sure the IP is direct. meaning, you shouldnt see a standard router DHCP adress on your router. Second, most routers give you an option to assign a device an IP instead of setting it up static in the device you are connecting, I would look to see if that is an option too. The problem is most likely a NAT issue. Some fixes work for people, some don't. Hope this made any sense.

I'd like to know why this is happening to me also. The worst thing that's happening to me so far is when I try to do DOA5 matches online and everytime I try to accept a match, rather than just letting me fight who I'm fighting, it kicks me out and says 'Opponent has declined match'.

I've been having the same problem except I don't do anything! Ill walk away for a second and it signs me out. I'm not on any game or app and its constantly doing this. It got to the point where I'm starting to use my Xbox for everything!
